To all whom it'may concern." I

Be it known that I, J Us'rUs R. KINNEY, a

citizen of the United States of America, and

a resident of Allston, in the" county of Suffolk and State of Massachusetts, have in; vented certain new and usefnl'Improvements in Strainers, of which the following is af specification.

This inventionrelates to strainersand par-f ticularly todevices of thiskind in whichtwo strainer baskets are provided; one" of which is adapted to be in commission at all times while the other'is being cleaned or repaired. The main object of the invention is to pro vide, in an a paratus of this class; means whereby the iquid will have a free passage from the inlet pipes: to eitherstrainer basket through a lower chamber, which chamber and basket may be readily cleaned out as desired, while the use of the other strainer basket may be continued.

The invention consists of a casingfhaving two compartments,- in each of I which a. strainer basket is positioned, and beneath each of which is a chamber communicating with the outer end of the strainer compartment, the inner ends of both compartments and chambers" communicating with a valve member which is adapted to be rotated to permit the liquid to flow from acomm'ojn inlet through either strainer basket to common outlet. v V I The invention further consists of certain novel features ofcons'tructio'n and arrangement of parts which will beunder'stoodrea'd ily by reference to the description of the drawings and to the claims tobe hereinafter given. H v t For the purpose; of illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found to ive satisfactory and reliable results, al though it isto' he'understo'od that the various instrumentalitiesfof whichthe invention consists can be variously arranged and organ ized, and thatthe' invention is not limited to the recise arra g ment and organization or theinstr'umentalities SliQW'n aiIid'd e scribed, except as required by the scope of the'appended claims.

Off h dr wingsi: i .7 Fi ure 1' represents] a ghori'zofntal eeetiiqn of a twin strainer? embodying the principles of the present invention. 1, v t A o Figure 2 represents a vertical section eftne same on line 2, '2 on 1, and

liigure3 represents a sideelevation of the same with thejcov'er plates removed;

Similar characters indicate like parts throughout the several figures of the drawe o III the drawings, 10 is a casing having therein avertical valve chamber 11, the lower end of which communicates with an inlet opening 12 v in axial alinement' therewith,"- whilean outlet opening 13 extends laterally from a point near the upper end thereof. 3

Theqcasing 10' is also provided with two" sets of passages communicating with' the valve chamber 11', each set consisting" of a horizontal chamber ll and a compartment 1'5 lbca'ted in the upper part of said horizontal chamber;

Each compartment 14 communicates with the" valve chamber 11 by means of a port lfitandeach compartment 15 communicates with said yalve' chamber by a port 17 The two sets of passages 14, 15 are separated from each other by a verticalwall 18. t The outer end of each horizontal chamber 14 is closed by means of a cover plate 19, securedto the casing 10 by means ofbolts 19 I The outer wall EZOof-each compartment 15 isprovided with a depression in which is disposed'the' annular member 21 supporting the euter nd or the basket 22; said annularmem ber 21'having a bale 23 formed thereon, by which the basket 22 may be removed from thej compartment 15- hen desired;

Each he iz'ental chamber; 14 has a drain openingf24 in the bottom thereof, normally closed by means of a' plug 25 By removing this p1u g'2'5, the horizontal chamber 14 may be drained of all liquid contained therein.

The valve chamber 11 is preferably coneshaped" as show'n'in Fig; 2, and has a coneshapedplug 26 positioned therein, this plug being divided into two seetion b me ns of the horizontalwall 27, the lower section'- 28 of which communicates at its lower end-with the inlet ope in 12.- This lower section 28 has" a lateral port'29adapted to regist r with either: port 16 leadin to one efthe hor'izontal ehamber'ele. p v v The upper section 30 of thevalve plug 26 is? pr v d d'wi a la er p rt 31 apt d te tegi's terwith a port 17 communicating with one of the compartments 15.- The port 31' is" substantially above the port 29 so that they will simultaneously register with the P ts 165-1 0f either s Qf.P eg 1 4e1 When the valve p1u'g'26 is in the position possible.

indicated in Fig. 1 of the drawings, the liq uid will pass through the inletopening 12 into the lower section 28 and through ports 29 and 16 into the horizontal chamber 14 the outlet opening 13.

The port 32 is of such a width as to register with the outlet opening 13 whenever the port 31 is in register with either of the ports 17. In other words, by turning the valve plug 26 about its axis, either set of passages 14, 15 may be brought into commission, while the other set is placed out of commission. When one set of passages is out of commission, the cover plate 19 of that set may be removed, thereby permitting the removal of the strainer basket 22 so that the same may be thoroughly cleansed before it is again returned to its position in the compartment 15 for further use.

The upper end of the valve chamber 11 is closedby the tubular head 33 having a gland 34 thereon of the usual stufiing box, through which extends a stem 35 of said valve plug 26. hen the valve plug 26 is moved about its axis so that the port 31 will be midway between the two ports 17, both sets of passages will be cut ofi" from the valve chamber 11. 7

By constructing twin strainers in the manner herein described, with the strainer basket horizontally disposed in'a compartment at the top ofthe horizontal chamber, the liquid to be strained is adapted to pass through the horizontal chamber upwardly into the open end of the strainer basket 22 and thence outwardly through the upper section of the valve plug to the discharge opening.

By this construction, the full benefit of the entire screen work of the basket 22 is made It is believed that the operation and many advantages of the invention will be understood readily without further description.
